CFEC108MK1
PIEZO FILTERS SURFACE MOUNTED CHIP PIEZOELECTRIC CERAMICS FILTERS FOR AM AND FM APPLICATIONS SFECV 10.7MHz, CFEC 10.8MHz Along with the development of the AM chip filter, IF filters for AM/FM radios have also been made smaller, thinner and in a chip configuration for surface mounting. This is one more example of Murata Electronics’ leadership in converting conventional electronic components to chip technology.
